Embodiment

[0023] The present invention controls the motors of the multi-fan indoor unit of the air conditioner separately, and provides a motor control method of the multi-fan indoor unit of the air conditioner, such as figure 1 shown.

[0024] In this embodiment, the multi-fan indoor unit of the air conditioner is provided with three motors 3 and three fans 4, and the structure of the fan components is as follows figure 2 As shown, it includes a front volute 1, a rear volute 2, three motors 3, and a fan 4 respectively installed on the motor shaft. The motor 3 and a fan 4 form a group, and three groups of motors 3 and fans 4. Installed up and down in the cavity formed by the assembly of the front volute 1 and the rear volute 2. After the assembly of the front volute 1 and the rear volute 2, three independent air channels 5 will be formed inside. The air channels 5 Both sides and the bottom of the fan are provided with air outlets 6, so that each group of motors 3 and fan 4 can adopt i...

Abstract

Provided is a motor control method of an air-conditioner multiple-fan indoor unit. A fan part of the air-conditioner multiple-fan indoor unit comprises N motors (3) and fans (4) respectively installed on a motor shaft, wherein N is greater than or equal to 2, one of the motors (3) and one of the fans (4) form a group, and the N motors (3) and the fans (4) are vertically arranged and respectively adopt independent air channels to supply air. The motor control method is characterized by comprising the following steps of 1 setting a target temperature Ts and a sampling period t, automatically detecting indoor environment temperature Tr within the sampling period t, automatically calculating an absolute value / DeltaT / = / Ts-Tr / of temperature difference Deltat, and setting default of / DeltaT / as reduction during initialization, 2 automatically judging whether / DeltaT / is reduced or not compared with previous sampling, executing a next step if the / DeltaT / is reduced or and executing the step 4 if the / DeltaT / is not reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a motor control method for multi-fan indoor units of an air conditioner. Background technique [0002] Due to a series of problems such as large noise, high energy consumption, and inability to meet the comfort level when the air-conditioning single-fan indoor unit is in operation, there have been air-conditioning multi-fan indoor units, such as an air conditioner disclosed in the Chinese invention patent application with the publication number CN101169267. Indoor unit, its fan components include at least two motors, and fans respectively installed on the motor shaft, said one motor and one fan form a group, and each group of motors and fans adopts an independent air duct to supply air. For the air-conditioning indoor unit of the above-mentioned fan components, the simultaneous operation of multiple low-power motors can fully achieve the operation effect of a single high...
